Abstract

An impurities elimination apparatus including a base plate, a first nozzle for removing impurities on the base plate using air suction, a glass substrate disposed on the base plate, and a second nozzle for coating the glass substrate with an organic material.

Claims (8)

1. A method of eliminating impurities, comprising the steps of:

initializing a first movable nozzle and a second movable nozzle at a coating stand-by location;

loading a glass substrate on a base plate;

coating the glass substrate with an organic material through the second nozzle while the first and second nozzles are moved along a linear transportation path from the coating stand-by location to a suction stand-by location;

removing the glass substrate coated with the organic material at the suction stand-by location; and

removing impurities on the base plate by air suction through the first nozzle while the first and second nozzles are moved along a linear transportation path from the suction stand-by location to a coating stand-by location, wherein the coating stand-by location and the suction stand-by location are at opposite ends of the base plate.

2. The method according to claim 1 , wherein the organic material includes a photo-resist.

3. The method according to claim 1 , wherein the base plate includes a stone surface plate.
